Wayne Rooney admits he would grab the chance to be captain of Manchester United and England "with both hands".
United will have a new skipper to appoint for next season, with defender Nemanja Vidic having already agreed a free transfer to Inter Milan.
There may also be a vacancy with England if Steven Gerrard, 33, decides to call it a day at international level after the World Cup.
Rooney said: "I've done it a few times and, if the (United) manager wants me to be the captain, I would have no problem with that. I would take it with both hands.
"However, it is down to the manager, because it's his decision on whoever he feels is the right person to lead the team. I'm sure he'll make that decision when the time comes.
"I think, whether you've got the armband or not, I always feel I'm quite vocal on the pitch. I try to help the players when I feel I can and say what I think."
In terms of England, the 28-year-old said it would be "an honour" to succeed Gerrard.
He added: "You don't know what Steven is going to do in the summer, only he knows.
"It would be a great honour to captain my country, but again, it's the manager's call and I'm sure he'll have a few contenders."
Rooney also said it is agony to see United's rivals Liverpool and Manchester City fight it out for the Premier League title.
